Here is a what if.....
I am operating in the UAE, and hold a UAE Licence...... for a period of several years, lets say 7, I take a GCAA PPC for my UAE based company, and operate under the GCAA FCL.
Is the GCAA Licence is a VALIDATION or FULL Licence.?
My understanding is that it is a VALIDATION.
Thus my GCAA licence ceases to exist when my UK CAA / JAR / ETC licence TR becomes extinct.
